Application April 29,

1 Claim.

This invention relates to an automatic lighter and gas saver which ismainly designed for use with a welding torch, the general object of theinvention being to provide a valve housing having inlets for receivingoxygen and acetylene or the like and outlets adapted to be connectedwith the torch, with manually operated valve means for controlling thesupply of gases through the device and also to provide a pilot valve forsupplying gas to the torch for the pilot flame thereof.

This invention consists in certain other features of construction and inthe combination and arrangement of several parts, to be hereinafterfully described, illustrated in the accompanying drawings andspecifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:-

Figure 1 is an elevation showing the invention in use with a torch.

Figure 2 is a longitudinal sectional view through the valve housing.

Figure 3 is a section on the line 3-3 of Figure 2.

Figure 4 is a section on theline 4--4 of Figure 3.

Figure 5 is a section on the line 5-5 of Figure 2.

Figure 6 is a view of the operating rod and the cross piece attachedthereto.

In these drawings the numeral l indicates a block of any suitablematerial enclosed in a casing 2 and said block in its front end isprovided with a chamber 3, and from the inner end of this chamberextends a pair of cylinders 4 and 5. The front portion of the walls ofthe cylinders are threaded to receive the nuts 6 with the packing means1 between each pair of nuts so that the front ends of the cylinders areclosed. A long passage 8 is formed in the block adjacent the cylinder 4and an intermediate part of this passage is connected to the cylinder 4by a port 9 while a substantially L-shaped passage H] extends from thecylinder 5 through the front end of the block. The front ends of thepassages 8 and H] receive the outlet tubes H which have the heads l2 onthe outer ends for receiving the fittings leading to the torch showngenerally at A, these fittings containing the valves 14 as shown inFigure 1. Each tube carries the jam nut I5 for engaging the fittings. Apassage 16 leads from the rear end of each cylinder through the 1935,Serial No. 18,970

rear end of the block where each passage receives the hose connectionl1, one of which is to be connected to a supply of oxygen and the otherto a supply of acetylene. The upper cylinder 4 and the passagesconnected therewith are connected with the supply of acetylene, whilethe lower cylinder 5 and the passages connected therewith are connectedwith the supply of oxygen. A pilot passage l8 extends from the acetylenepassage I6 into the passage 8 and is controlled by a screw valve l9 sothat by slightly opening this valve l9 acetylene gas can be supplied tothe pilot of the torch.

A pair of piston valves 20 are located in the cylinders 4 and 5 forcontrolling communication between the passages l6 and the passages B andl0 and these pistons are connected to the rods 2i which pass through thenuts 6 and the packing 1 and their outer ends are connected by a crosspiece 22 to the center of which a rod 23 is connected by the nuts 24,the rod passing through a bore in the center of the block into acylinder 25 at the rear end of the block. A spring 26 encircles the rodand is located in the cylinder 25 and a washer 21 is held in position onthe rod by the nut 28, the washer formin a bearing for the spring andthe spring acting to hold the parts with the valve pistons 20 in closedposition as shown in Figure 2. A coupling 29 is connected with the rearend of the rod and connects with a slide button 30 which passes througha slot 3] in the casing 2 as shown in Figure 3, so that by adjustingthis button the valves can be moved to open or closed position and bothvalves will be adjusted at the same time.

Thus it will be seen that when the torch is not in use a small pilotlight will be burning at the tip of the torch and then when it isdesired to use the torch the button 30 is moved to a position to openthe valves 20 so that the gases will flow to the torch to produce awelding flame.

This lighter and gas saver makes an automatic What is claimed is:-

In a device of the class described, a body hav ing a recess in each endthereof, a pair of spaced longitudinally extending cylinders in the bodyopening out into one recess, means for closing the outer end of eachcylinder, a piston in each cylinder, rods connected with the pistons andV passing through the closing means, a cross piece connecting the outerends of the rods together, a stem having one end connected with thecentral part of the cross piece, said stem being slidably supported inthe central part of the body, a cylinder opening out into the otherrecess and into which the stem extends, a head on the stem slidablyarranged in the last mentioned cylinder, a spring'in said last mentionedcylinder bearing ing to a point adjacent an inlet passage, and the bodyhaving a lateral port therein connecting said extension with said inletpassage, and a screw valve passing through a side part of the body andcontrolling the port.
